Sasthamkotta Lake is a very clean and green lake in Kollam, Kerala, and truly deserves its place as a beautiful waterbody. The premises are well maintained, and getting there is pretty easy. The place offers great photo opportunities, even in the middle of a very harsh summer, thanks to the excellent tree cover along the banks. The lake is named after the ancient Sastha temple (a pilgrimage center) located on its bank. It is surrounded by hills on all sides. The wetland supports 27 species of freshwater fishes and two genera of prawns. The lake is a designated wetland of international importance under the Ramsar Convention since November 2002.
